Description

本発明は、物体間を開閉自在に支持するヒンジ装置がそのシャフト部が挿入される取付穴から抜けるのを防ぐヒンジロック機構に関するものである。   The present invention relates to a hinge locking mechanism that prevents a hinge device that openably and closably supports between objects from coming out of a mounting hole into which a shaft portion is inserted.

従来この種のヒンジロック機構としては、例えば、特許文献１に開示された、トイレ便座の取付構造におけるものがある。   Conventionally, as a hinge lock mechanism of this type, there is, for example, one in a toilet seat attachment structure disclosed in Patent Document 1.

同文献におけるトイレ便座の取付構造では、便座や便蓋におけるホルダ部の取付穴にシャフト状をしたヒンジ装置のアダプタ部材が挿入された後、アダプタ部材に設けられた溝にスプリングクリップの脚部が嵌められる。この際、スプリングクリップの脚部は、便座や便蓋のホルダ部側方に開口した挿入孔を通される。スプリングクリップの脚部がこの挿入孔を通ってアダプタ部材に設けられた溝に嵌められることで、ヒンジ装置は取付穴から抜けなくなり、便座や便蓋に固定される。   In the mounting structure of the toilet seat in the same document, after the adapter member of the hinge device having a shaft shape is inserted into the mounting hole of the holder portion in the toilet seat or lid, the leg of the spring clip is in the groove provided in the adapter member. Be fitted. At this time, the leg portion of the spring clip is passed through the insertion hole opened to the side of the toilet seat or the holder portion of the toilet lid. By fitting the leg portion of the spring clip into the groove provided in the adapter member through the insertion hole, the hinge device does not come out of the mounting hole and is fixed to the toilet seat or the toilet lid.

独国特許出願公開第１００５１８０５号明細書German Patent Application Publication No. 10051805

しかしながら、特許文献１に開示された上記従来のヒンジロック機構では、ヒンジ装置をホルダ部の取付穴から抜けなくするため、スプリングクリップ等の固定具をヒンジ装置とは別に用意する必要がある。また、スプリングクリップをアダプタ部材の溝に嵌めるために、便座や便蓋のホルダ部側方に取付穴に通じる挿入孔を設ける必要もある。したがって、上記従来のヒンジロック機構では、ヒンジ装置を使ったトイレの製造時、スプリングクリップ等の固定具をヒンジ装置とは別個に管理する管理工程が必要になる。また、便座や便蓋の製造時、ホルダ部に挿入孔を設ける加工工程も必要になる。このため、従来、これらの管理工程や加工工程がトイレや便座・便蓋の製造時におけるコスト面および作業面の負担となっていた。   However, in the conventional hinge lock mechanism disclosed in Patent Document 1, in order to prevent the hinge device from coming out of the mounting hole of the holder, it is necessary to prepare a fixing tool such as a spring clip separately from the hinge device. Also, in order to fit the spring clip into the groove of the adapter member, it is necessary to provide an insertion hole communicating with the mounting hole on the side of the holder portion of the toilet seat or toilet lid. Therefore, in the above-mentioned conventional hinge lock mechanism, at the time of manufacture of a toilet using a hinge device, a management process which manages fixtures, such as a spring clip, separately from a hinge device is needed. Moreover, at the time of manufacture of a toilet seat or a toilet lid, the processing process which provides an insertion hole in a holder part is also needed. For this reason, conventionally, these management steps and processing steps have been the burden of cost and work in manufacturing the toilet, toilet seat and lid.

本発明はこのような課題を解決するためになされたもので、
物体間を開閉自在に支持するヒンジ装置がそのシャフト部が挿入される取付穴から抜けるのを防ぐヒンジロック機構において、
シャフト部に嵌合する内径形状を有する第１内径部と、シャフト部の外径より小さな内径をして第１内径部の最深部に第１内径部に連なって開口する第２内径部とが取付穴に形成され、
第２内径部の内径と同等以上の外径をして弾性を有し、第２内径部に差し込まれて外周が第２内径部の内周に引っ掛かる係止部材をシャフト部の先端に備える
ことを特徴とする。The present invention has been made to solve such problems.
In a hinge lock mechanism which prevents a hinge device for openably and closably supporting objects from coming out of a mounting hole into which the shaft portion is inserted,
A first inner diameter portion having an inner diameter shape fitted to the shaft portion, and a second inner diameter portion having an inner diameter smaller than the outer diameter of the shaft portion and being continuous with the first inner diameter portion at the deepest portion of the first inner diameter portion Formed in the mounting hole,
An outer diameter equal to or larger than the inner diameter of the second inner diameter portion has elasticity, and a locking member which is inserted into the second inner diameter portion and whose outer periphery is caught on the inner periphery of the second inner diameter portion is provided at the tip of the shaft portion It is characterized by

本構成によれば、ヒンジ装置のシャフト部が取付穴に挿入されると、シャフト部が第１内径部に嵌合すると共に、シャフト部の先端に備えられる係止部材が第２内径部に差し込まれる。この際、係止部材はその弾性によって撓んで弾性変形して第２内径部に入り込み、その外周が第２内径部の内周に引っ掛かる。先端にこの係止部材を備えるシャフト部は、取付穴から抜き取る力がかかっても、係止部材が第２内径部の内周に引っ掛かってこの抜き取る力に対抗するので、取付穴から抜けなくなり、ヒンジ装置は取付穴から抜けなくなる。したがって、従来のスプリングクリップ等の固定具を使用することなく、ヒンジ装置を取付穴から抜けなくすることが出来る。このため、スプリングクリップ等の固定具をヒンジ装置と別に用意する必要がなくなり、スプリングクリップ等の固定具をヒンジ装置とは別個に管理する管理工程を削減することが出来る。また、スプリングクリップ等の固定具をホルダ部に通すための挿入孔が不要になり、ホルダ部に挿入孔を設ける加工工程を削減することが出来る。この結果、ヒンジ装置を使ったトイレの製造時や、便座・便蓋の製造時におけるコスト面および作業面の負担を軽減することが出来る。   According to this configuration, when the shaft portion of the hinge device is inserted into the mounting hole, the shaft portion is fitted into the first inner diameter portion, and the locking member provided at the tip of the shaft portion is inserted into the second inner diameter portion. Be At this time, the locking member is bent and elastically deformed by its elasticity and enters the second inner diameter portion, and the outer periphery thereof is caught on the inner periphery of the second inner diameter portion. The shaft portion provided with the locking member at the tip does not come out of the mounting hole because the locking member is caught on the inner periphery of the second inner diameter portion and resists the pulling out force even if a force to pull out from the mounting hole is applied. The hinge device does not come out of the mounting hole. Therefore, the hinge device can be prevented from coming out of the mounting hole without using a fixing device such as a conventional spring clip. For this reason, it is not necessary to prepare fixtures, such as a spring clip, separately from a hinge apparatus, and the management process which manages fixtures, such as a spring clip, separately from a hinge apparatus can be reduced. Moreover, the insertion hole for passing fixing tools, such as a spring clip, through a holder part becomes unnecessary, and the processing process which provides an insertion hole in a holder part can be reduced. As a result, it is possible to reduce the burden of cost and work in manufacturing the toilet using the hinge device, and in manufacturing the toilet seat and lid.

また、本発明は、係止部材が、外周に複数の凸部が形成された円盤状部材、または、外周に複数の切り欠き部が形成された円盤状部材、または、外周が円形をした円盤状部材であって、外周がシャフト部側に傾斜していることを特徴とする。   Further, according to the present invention, the locking member is a disk-like member having a plurality of projections formed on the outer periphery, or a disk-like member having a plurality of cutouts formed on the outer periphery, or a disk having a circular outer periphery. And the outer periphery is inclined toward the shaft portion.

本構成によれば、シャフト部に取付穴から抜き取る力がかかると、係止部材の外周が第２内径部の内周に噛み込む。このため、係止部材がシャフト部を抜き取る力に対抗する力は大きくなり、ヒンジ装置は堅固に取付穴から抜けなくなる。また、係止部材の外周がシャフト部側に傾斜しているので、シャフト部に取付穴から抜き取る力がかかると、係止部材の外周は第２内径部の内周により鋭く噛み込む。このため、ヒンジ装置はより堅固に取付穴から抜けなくなる。また、係止部材の外周がシャフト部側に傾斜していると、シャフト部を取付穴に挿入する際、係止部材はスムーズに第２内径部に入り込み、ヒンジ装置の取付穴への組み込み性が向上する。   According to this configuration, when the shaft portion is pulled out from the mounting hole, the outer periphery of the locking member is engaged with the inner periphery of the second inner diameter portion. For this reason, the force against the force with which the locking member pulls out the shaft portion increases, and the hinge device does not firmly come out of the mounting hole. Further, since the outer periphery of the locking member is inclined toward the shaft portion side, when the shaft portion is pulled out from the mounting hole, the outer periphery of the locking member is sharply bitten by the inner periphery of the second inner diameter portion. Because of this, the hinge device does not come out of the mounting hole more firmly. Further, when the outer periphery of the locking member is inclined toward the shaft portion side, when inserting the shaft portion into the mounting hole, the locking member smoothly enters the second inner diameter portion, and the incorporation of the hinge device into the mounting hole Improve.

また、本発明は、第２内径部の内径より小さな外径をして第２内径部に差し込まれる支持柱がシャフト部の先端に突出して形成され、
係止部材が支持柱に支えられてシャフト部の先端に取り付けられる
ことを特徴とする。Further, according to the present invention, a support column inserted into the second inner diameter portion with an outer diameter smaller than the inner diameter of the second inner diameter portion is formed to project from the tip of the shaft portion,
The locking member is supported by the support column and attached to the tip of the shaft portion.

支持柱を介してシャフト部の先端に係止部材が取り付けられる本構成によれば、係止部材のシャフト部先端への取り付けが容易になると共に、係止部材の撓み代を係止部材のシャフト部側に確保することが出来る。   According to the present configuration in which the locking member is attached to the tip of the shaft portion via the support column, attachment of the locking member to the tip of the shaft portion is facilitated, and the deflection margin of the locking member is used as the shaft of the locking member It can be secured on the part side.

また、本発明は、係止部材が、支持柱からシャフト部の軸方向に抜けず、かつ、支持柱に回転自在に、支持柱に取り付けられることを特徴とする。   Further, the present invention is characterized in that the locking member is attached to the support column so as not to slip out of the support column in the axial direction of the shaft portion and to be rotatable on the support column.

本構成によれば、係止部材が第２内径部の内周に引っ掛かって第２内径部の内周に固定されている状態においても、係止部材を支持する支持柱は係止部材に対して回転可能な状態に保たれる。したがって、支持柱が先端に設けられたシャフト部は、係止部材が第２内径部の内周に固定されている状態においても、係止部材とは独立に回転可能であり、ヒンジ装置が開閉自在に支持する一方の物体と共に回転する。このため、ヒンジ装置が開閉自在に支持する一方の物体（例えば便蓋）とは別の物体（例えば便座）に取付穴の第２内径部が形成され、その第２内径部に係止部材が固定される場合、一方の物体に形成された取付穴の第１内径部に嵌合するシャフト部が一方の物体と共に回転しても、係止部材は、シャフト部の回転に伴って回転しない。よって、係止部材がシャフト部の回転に伴って回転することで、係止部材が固定されている別の物体との間に摩擦を生じて、別の物体を傷付けることはない。また、別の物体が回転して別の物体と共に係止部材が回転しても、その回転に伴ってシャフト部が回転することはないため、ヒンジ装置が別の物体の回転に影響されることはない。   According to this configuration, even in the state where the locking member is caught on the inner periphery of the second inner diameter portion and fixed to the inner periphery of the second inner diameter portion, the support column supporting the locking member is against the locking member Can be kept rotatable. Therefore, the shaft portion provided with the support column at the tip is rotatable independently of the locking member even in the state where the locking member is fixed to the inner periphery of the second inner diameter portion, and the hinge device opens and closes. It rotates with one of the freely supported objects. For this reason, the second inner diameter portion of the mounting hole is formed in an object (for example, a toilet seat) different from one of the objects (for example, the toilet lid) that the hinge device supports openably and closably. When fixed, even if the shaft portion fitted in the first inner diameter portion of the mounting hole formed in one object rotates with one object, the locking member does not rotate with the rotation of the shaft portion. Thus, the rotation of the locking member with the rotation of the shaft does not cause friction with another object to which the locking member is fixed, and does not damage another object. In addition, even if another object rotates and the locking member rotates with another object, the hinge does not rotate with the rotation, so that the hinge device is affected by the rotation of the other object. There is no.

また、本発明は、支持柱が、シャフト部と別体に形成されて外周に雄ネジが形成され、シャフト部の先端にシャフト部の軸方向に開口したネジ穴の内周に形成された雌ネジと螺合して、シャフト部の先端に取り付けられることを特徴とする。   Further, according to the present invention, the support post is formed separately from the shaft portion, and an external thread is formed on the outer periphery, and a female is formed on the inner periphery of the screw hole opened in the axial direction of the shaft portion at the tip of the shaft portion. It is characterized by screwing with a screw and being attached to the tip of a shaft part.

本構成によれば、シャフト部と別体に形成された支持柱がシャフト部の先端に螺合して取り付けられるため、支持柱をシャフト部に対して相対的に回すことで、支持柱がシャフト部の先端から突出する長さを調整することができる。このため、係止部材が第２内径部の内周に引っ掛かって固定される位置を、第２内径部の深さに応じて所望の位置に設定することができる。また、第２内径部の実際の形状に応じて、係止部材の第２内径部内周への引っ掛かり具合が丁度よい深さに、係止部材の固定位置を設定することができる。   According to this configuration, since the support column separately formed from the shaft portion is screwed to the tip of the shaft portion, the support column can be a shaft by rotating the support column relative to the shaft portion. The length of projection from the tip of the part can be adjusted. For this reason, the position where the locking member is caught and fixed on the inner periphery of the second inner diameter portion can be set to a desired position according to the depth of the second inner diameter portion. Further, according to the actual shape of the second inner diameter portion, the fixing position of the locking member can be set to such a depth that the degree of engagement of the locking member to the inner periphery of the second inner diameter portion is just right.

また、本発明は、支持柱が、シャフト部と別体に形成されて、シャフト部の先端にシャフト部の軸方向に開口した開口部に出し入れ自在に収納され、開口部に内蔵された弾性部材によって第２内径部の深部側に付勢されることを特徴とする。   Further, according to the present invention, an elastic member in which the support column is formed separately from the shaft portion, is accommodated at an end of the shaft portion at the tip end of the shaft portion so as to be freely inserted in and out. , And is urged toward the deep side of the second inner diameter portion.

本構成によれば、シャフト部が取付穴に挿入されて係止部材が第２内径部に差し込まれた状態において、開口部に内蔵された弾性部材によって第２内径部の深部側に支持柱が付勢されることで、係止部材も第２内径部の深部側に付勢される。このため、ヒンジ装置の取付穴への組み込み後において、係止部材が第２内径部の深部側に常に付勢されることで、係止部材は第２内径部から抜けないその深部側の方向へ常に押されるので、係止部材の第２内径部内周への保持安定性が高められる。また、ヒンジ装置の取付穴への組み込み時において、シャフト部先端の係止部材が取付穴の周囲に当たると、係止部材が一旦引っ込むので、この引っ込みがシャフト部先端を取付穴に挿入する案内になって、シャフト部先端を取付穴に挿入し易くなり、ヒンジ装置の取付穴への組み込み性が向上する。   According to this configuration, in a state in which the shaft portion is inserted into the mounting hole and the locking member is inserted into the second inner diameter portion, the support pillar is provided on the deep side of the second inner diameter portion by the elastic member incorporated in the opening. By being biased, the locking member is also biased to the deep side of the second inner diameter portion. Therefore, the locking member is always urged to the deep side of the second inner diameter portion after the hinge device is installed in the mounting hole, and the direction of the deep side where the locking member does not come off the second inner diameter portion The holding stability of the locking member to the inner circumference of the second inner diameter portion is enhanced. In addition, when the locking member at the tip of the shaft portion hits the periphery of the mounting hole at the time of installation in the mounting hole of the hinge device, the locking member once retracts, and this retraction leads to a guide for inserting the shaft tip into the mounting hole. Thus, the tip of the shaft portion can be easily inserted into the mounting hole, and the incorporation of the hinge device into the mounting hole is improved.

本発明によれば、スプリングクリップ等の固定具をヒンジ装置とは別個に管理する管理工程、および、ホルダ部に挿入孔を設ける加工工程を削減することが出来、トイレの製造時や、便座・便蓋の製造時におけるコスト面および作業面の負担が軽減される。   According to the present invention, it is possible to reduce a management step of managing fixing tools such as spring clips separately from the hinge device and a processing step of providing an insertion hole in the holder portion. The burden of cost and work at the time of manufacture of the toilet lid is reduced.

ロータリーダンパ部１２の端部に突出するシャフト部１４は、便蓋の不図示の取付穴を通された後、ホルダ部２０，３０の取付穴２０ａ，３０ａに挿入される。   The shaft portion 14 protruding from the end of the rotary damper portion 12 is inserted into the mounting holes 20a and 30a of the holder portions 20 and 30 after passing through the mounting holes (not shown) of the toilet lid.

取付穴２０ａには第１内径部２０a1と第２内径部２０a2とが形成されている。第１内径部２０a1は、シャフト部１４に嵌合する内径形状を有する。シャフト部１４は、金属や樹脂等から形成され、円弧状の周面が対向した案内曲面部１４ａと、平面が平行に対向した平面部１４ｂとを備える。第１内径部２０a1の内周には、案内曲面部１４ａに対応した形状の円弧部２０a11と、平面部１４ｂに対応して対向する壁部２０a12とが形成されている。第２内径部２０a2は、シャフト部１４における案内曲面部１４ａの外径φ11より小さな内径φ２（φ２＜φ11）をした中空円筒状をしており、第１内径部２０a1の最深部に第１内径部２０a1に連なって開口している。この第２内径部２０a2は、図３（ｃ）に示す断面図のように、ホルダ部２０を貫通して形成される場合もある。   A first inner diameter portion 20a1 and a second inner diameter portion 20a2 are formed in the mounting hole 20a. The first inner diameter portion 20a1 has an inner diameter shape fitted to the shaft portion 14. The shaft portion 14 is formed of metal, resin, or the like, and includes a guide curved surface portion 14a in which circular arc-shaped circumferential surfaces face each other, and a flat surface portion 14b in which flat surfaces face in parallel. On the inner periphery of the first inner diameter portion 20a1, an arc portion 20a11 having a shape corresponding to the guide curved surface portion 14a and a wall portion 20a12 opposed to the flat surface portion 14b are formed. The second inner diameter portion 20a2 has a hollow cylindrical shape with an inner diameter φ2 (φ2 <φ11) smaller than the outer diameter φ11 of the guide curved surface portion 14a in the shaft portion 14, and the first inner diameter in the deepest portion of the first inner diameter portion 20a1 It opens in series with the part 20a1. The second inner diameter portion 20a2 may be formed penetrating the holder portion 20 as shown in the cross-sectional view of FIG. 3 (c).

また、取付穴３０ａには第１内径部３０a1と第２内径部３０a2とが形成されている。第２内径部３０a2は、取付穴２０ａの第２内径部２０a2と同様な開口形状をしており、図３（ｃ）に示すように、ホルダ部３０を貫通して形成される場合もある。しかし、第１内径部２０a1に対応する第１内径部３０a1は、円弧部２０a11と同じ直径の中空円筒状をしており、シャフト部１４の平面部１４ｂに嵌合する壁部２０a12のような壁部を備えていない。便座の取付穴３０ａには便蓋の不図示の取付穴が連通して設けられ、この便蓋の不図示の取付穴には、第１内径部２０a1と同様な開口形状をした不図示の第１内径部が形成されている。第２内径部３０a2は、第１内径部３０a1の最深部に、これら不図示の第１内径部および第１内径部３０a1に連なって開口する。   Further, a first inner diameter portion 30a1 and a second inner diameter portion 30a2 are formed in the mounting hole 30a. The second inner diameter portion 30a2 has an opening shape similar to the second inner diameter portion 20a2 of the attachment hole 20a, and may be formed penetrating the holder portion 30 as shown in FIG. 3 (c). However, the first inner diameter portion 30a1 corresponding to the first inner diameter portion 20a1 has a hollow cylindrical shape with the same diameter as the arc portion 20a11, and a wall such as the wall portion 20a12 fitted to the flat portion 14b of the shaft portion 14 Not equipped with a department. A mounting hole (not shown) of the toilet lid is provided in communication with the mounting hole 30a of the toilet seat, and a mounting hole (not shown) of the toilet lid has an opening shape similar to the first inner diameter portion 20a1. An inner diameter portion is formed. The second inner diameter portion 30a2 is opened at the deepest portion of the first inner diameter portion 30a1 continuously to the first inner diameter portion and the first inner diameter portion 30a1 (not shown).

シャフト部１４は先端にディスクフック１５を係止部材として備える。ディスクフック１５は、図４（ｂ）に正面図、図４（ｃ）に側面図が示され、外周に複数の凸部１５ａが形成された金属製の円盤状部材からなり、外周がシャフト部１４側に傾斜している。また、正面視で鏡面対称になっている。このディスクフック１５は、取付穴２０ａ，３０ａの第２内径部２０a2，３０a2の内径φ２と同等以上の外径φ３（φ３≧φ２）をして、弾性を有し、第２内径部２０a2，３０a2に差し込まれて、外周が第２内径部２０a2，３０a2の内周に引っ掛かる。   The shaft portion 14 has a disc hook 15 at its tip as a locking member. The disc hook 15 is a front view in FIG. 4 (b) and a side view in FIG. 4 (c), and is formed of a metal disc-like member having a plurality of convex portions 15a formed on the outer periphery. It is inclined to the 14 side. In addition, it is mirror-symmetrical in front view. The disc hook 15 has an outer diameter φ3 (φ3 ≧ φ2) equal to or larger than the inner diameter φ2 of the second inner diameter portions 20a2 and 30a2 of the mounting holes 20a and 30a, and has elasticity, and the second inner diameter portions 20a2 and 30a2 The outer periphery is caught on the inner periphery of the second inner diameter portions 20a2 and 30a2.

本実施形態では、図４（ａ）の側面図に示すように、シャフト部１４の先端に、第２内径部２０a2，３０a2に差し込まれる円柱状の支持柱１６が突出して形成されている。支持柱１６は、第２内径部２０a2，３０a2の内径φ２より小さな外径φ４（φ４＜φ２）をしている。この外径φ４は、本実施形態では、シャフト部１４における案内曲面部１４ａの外径φ11の５０％以下（φ４≦０．５×φ11）で、かつ、平面部１４ｂの外径φ12の７０％以下（φ４≦０．７×φ12）に設定される。ディスクフック１５は、この支持柱１６に支えられて、シャフト部１４の先端に取り付けられる。本実施形態では、支持柱１６の先端に支持柱１６より細い直径の円柱状のカシメ代１６ａが、ディスクフック１５の円盤部の厚みｔより５０〜８０％大きい突出長さＬ（＝１．５ｔ〜１．８ｔ）で形成されている。ディスクフック１５の支持柱１６への取り付けは、ディスクフック１５の円盤部中央に開口した穴１５ｂにカシメ代１６ａが挿入され、ディスクフック１５の円盤部の厚みｔより突出するカシメ代１６ａの先端外周囲が、スピンカシメやプレスカシメ等によって外周に拡がる方向に潰されて、行われる。このカシメにより、ディスクフック１５は、支持柱１６からシャフト部１４の軸方向に抜けず、かつ、支持柱１６に回転自在に、支持柱１６に取り付けられる。   In the present embodiment, as shown in the side view of FIG. 4A, a cylindrical support post 16 to be inserted into the second inner diameter portion 20a2 and 30a2 is formed to protrude at the tip of the shaft portion 14. The support column 16 has an outer diameter φ4 (φ4 <φ2) smaller than the inner diameter φ2 of the second inner diameter portions 20a2 and 30a2. In the present embodiment, the outer diameter φ4 is 50% or less (φ4 ≦ 0.5 × φ11) of the outer diameter φ11 of the curved guide portion 14a of the shaft portion 14 and 70% of the outer diameter φ12 of the flat portion 14b. The following is set (φ4 ≦ 0.7 × φ12). The disc hook 15 is supported by the support post 16 and attached to the tip of the shaft portion 14. In the present embodiment, a projecting length L (= 1.5 t) which is 50 to 80% larger than the thickness t of the disc portion of the disc hook 15 at the tip of the support post 16 is a cylindrical caulking margin 16a having a diameter smaller than the support post 16 ~ 1.8t) is formed. For attachment of the disc hook 15 to the support column 16, the caulking margin 16a is inserted into the hole 15b opened at the center of the disc portion of the disc hook 15, and the tip of the caulking margin 16a protrudes beyond the thickness t of the disc portion of the disc hook 15. The circumference is crushed by spin caulking, press caulking or the like in the direction of spreading to the outer circumference. By this caulking, the disc hook 15 is attached to the support post 16 so as not to slip out of the support post 16 in the axial direction of the shaft portion 14 and to be rotatable on the support post 16.

支持柱１６、ディスクフック１５、および第２内径部２０a2，３０a2は、本発明の一実施形態によるヒンジロック機構を構成する。このヒンジロック機構は、便座および便器の物体間、並びに便蓋および便器の物体間を開閉自在に支持するヒンジ装置１０，１０’が、そのシャフト部１４が挿入される取付穴２０ａ，３０ａから抜けるのを防ぐ。   The support post 16, the disc hook 15, and the second inner diameter portions 20a2 and 30a2 constitute a hinge lock mechanism according to an embodiment of the present invention. The hinge lock mechanism allows the hinge device 10, 10 'for openably supporting between the toilet seat and the toilet bowl object and the toilet lid and the toilet bowl object to be removed from the mounting holes 20a, 30a into which the shaft portion 14 is inserted. To prevent.

図５（ａ）は、ヒンジ装置１０のシャフト部１４がホルダ部２０の取付穴２０ａに挿入される前の状態における一部破断側面図、図５（ｂ）は、シャフト部１４が取付穴２０ａに挿入された後の状態における一部破断側面図である。なお、図５において図３と同一部分には同一符号を付してその説明は省略する。   5 (a) is a partially broken side view before the shaft portion 14 of the hinge device 10 is inserted into the mounting hole 20a of the holder portion 20, and FIG. 5 (b) is a shaft portion 14 having the mounting hole 20a. It is a partially broken side view in the state after being inserted in. The same reference numerals as in FIG. 3 denote the same parts in FIG. 5, and a description thereof will be omitted.

図５（ａ）に示す状態からヒンジ装置１０のシャフト部１４が取付穴２０ａに挿入されると、図５（ｂ）に示す状態のように、シャフト部１４が第１内径部２０a1に嵌合すると共に、シャフト部１４の先端に備えられるディスクフック１５が第２内径部２０a2に差し込まれる。この際、ディスクフック１５はその弾性によって撓んで弾性変形して第２内径部２０a2に入り込み、その外周が第２内径部２０a2の内周に引っ掛かる。先端にこのディスクフック１５を備えるシャフト部１４は、取付穴２０ａから抜き取る力がかかっても、ディスクフック１５が第２内径部２０a2の内周に引っ掛かってこの抜き取る力に対抗するので、取付穴２０ａから抜けなくなり、ヒンジ装置１０は取付穴２０ａから抜けなくなる。   When the shaft portion 14 of the hinge device 10 is inserted into the mounting hole 20a from the state shown in FIG. 5A, the shaft portion 14 is fitted to the first inner diameter portion 20a1 as shown in FIG. 5B. At the same time, the disc hook 15 provided at the tip of the shaft portion 14 is inserted into the second inner diameter portion 20a2. At this time, the disc hook 15 is bent and elastically deformed by its elasticity and enters the second inner diameter portion 20a2, and the outer periphery thereof is caught on the inner periphery of the second inner diameter portion 20a2. The shaft portion 14 provided with the disc hook 15 at the tip end can catch the disc hook 15 on the inner periphery of the second inner diameter portion 20a2 even if a force to withdraw from the mounting hole 20a is applied, and thus opposes the withdrawal force. The hinge device 10 does not come out of the mounting hole 20a.

ヒンジ装置１０’も同様にして、シャフト部１４が取付穴３０ａに挿入されて、ディスクフック１５が第２内径部３０a2に差し込まれることで、取付穴３０ａから抜けなくなる。なお、ヒンジ装置１０，１０’を取付穴２０ａ，３０ａからディスクフック１５の対抗力より大きな力で引き抜くと、取付穴２０ａ，３０ａが塑性変形してホルダ部２０，３０からヒンジ装置１０，１０’を取り外すことができる。   Similarly, in the hinge device 10 ', when the shaft portion 14 is inserted into the mounting hole 30a and the disc hook 15 is inserted into the second inner diameter portion 30a2, it does not come out of the mounting hole 30a. When the hinges 10, 10 'are pulled out of the mounting holes 20a, 30a with a force larger than the opposing force of the disc hook 15, the mounting holes 20a, 30a are plastically deformed and the holder portions 20, 30 to the hinges 10, 10'. Can be removed.

したがって、本実施形態によるヒンジロック機構によれば、従来のスプリングクリップ等の固定具を使用することなく、ヒンジ装置１０，１０’を取付穴２０ａ，３０ａから抜けなくすることが出来る。このため、スプリングクリップ等の固定具をヒンジ装置１０，１０’と別に用意する必要がなくなり、スプリングクリップ等の固定具をヒンジ装置１０，１０’とは別個に管理する管理工程を削減することが出来る。また、スプリングクリップ等の固定具をホルダ部２０，３０に通すための挿入孔が不要になり、ホルダ部２０，３０に挿入孔を設ける加工工程を削減することが出来る。この結果、ヒンジ装置１０，１０’を使ったトイレの製造時や、便座・便蓋の製造時におけるコスト面および作業面の負担を軽減することが出来る。また、取付穴２０ａ，３０ａの第２内径部２０a2，３０a2は、一定以上の深さがあればよく、内径φ２に精度は必要なく、精緻な仕上げは必要とされない。   Therefore, according to the hinge lock mechanism according to the present embodiment, it is possible to prevent the hinge devices 10 and 10 'from coming out of the mounting holes 20a and 30a without using a fixing tool such as a conventional spring clip. For this reason, it is not necessary to prepare a fixing tool such as a spring clip separately from the hinge devices 10 and 10 ', and it is possible to reduce a management process for managing the fixing device such as a spring clip separately from the hinge devices 10 and 10'. It can. Moreover, the insertion hole for passing fixing tools, such as a spring clip, in holder parts 20 and 30 becomes unnecessary, and the processing process which provides an insertion hole in holder parts 20 and 30 can be reduced. As a result, it is possible to reduce the cost and the work surface burden at the time of manufacturing the toilet using the hinge devices 10 and 10 'and at the time of manufacturing the toilet seat and the toilet lid. Further, the second inner diameter portions 20a2 and 30a2 of the mounting holes 20a and 30a need only have a certain depth or more, and the inner diameter φ2 does not require accuracy, and a fine finish is not required.

また、本実施形態によるヒンジロック機構によれば、シャフト部１４に取付穴２０ａ，３０ａから抜き取る力がかかると、ディスクフック１５の外周の凸部１５ａが第２内径部２０a2，３０a2の内周に噛み込む。このため、ディスクフック１５がシャフト部１４を抜き取る力に対抗する力は大きくなり、ヒンジ装置１０，１０’は堅固に取付穴２０ａ，３０ａから抜けなくなる。また、ディスクフック１５の外周がシャフト部１４側に傾斜しているので、シャフト部１４に取付穴２０ａ，３０ａから抜き取る力がかかると、ディスクフック１５の外周の凸部１５ａは第２内径部２０a2，３０a2の内周により鋭く噛み込む。このため、ヒンジ装置１０，１０’はより堅固に取付穴２０ａ，３０ａから抜けなくなる。また、ディスクフック１５の外周がシャフト部１４側に傾斜していると、シャフト部１４を取付穴２０ａ，３０ａに挿入する際、ディスクフック１５はスムーズに第２内径部２０a2，３０a2に入り込み、ヒンジ装置１０，１０’の取付穴２０ａ，３０ａへの組み込み性が向上する。   Further, according to the hinge lock mechanism according to the present embodiment, when the shaft portion 14 is pulled out from the mounting holes 20a and 30a, the convex portion 15a on the outer periphery of the disc hook 15 is on the inner periphery of the second inner diameter portion 20a2 and 30a2. Bite. For this reason, the force with which the disc hook 15 opposes the force with which the shaft portion 14 is pulled out increases, and the hinge devices 10 and 10 'do not come out of the mounting holes 20a and 30a firmly. Further, since the outer periphery of the disc hook 15 is inclined toward the shaft portion 14, when the shaft portion 14 receives a force for removal from the mounting holes 20 a and 30 a, the convex portion 15 a of the outer periphery of the disc hook 15 has the second inner diameter portion 20 a 2 , 30a2 and bite more sharply. Therefore, the hinges 10 and 10 'do not come out of the mounting holes 20a and 30a more firmly. When the outer periphery of the disc hook 15 is inclined toward the shaft portion 14, the disc hook 15 smoothly enters the second inner diameter portion 20a2 and 30a2 when inserting the shaft portion 14 into the mounting holes 20a and 30a, and the hinge is The incorporation of the device 10, 10 'into the mounting holes 20a, 30a is improved.

また、本実施形態によるヒンジロック機構によれば、支持柱１６を介してシャフト部１４の先端にディスクフック１５が取り付けられるので、ディスクフック１５のシャフト部１４先端への取り付けが容易になると共に、ディスクフック１５の撓み代をディスクフック１５のシャフト部１４側に確保することが出来る。   Further, according to the hinge lock mechanism according to the present embodiment, since the disc hook 15 is attached to the tip of the shaft portion 14 via the support post 16, attachment of the disc hook 15 to the tip of the shaft portion 14 is facilitated. The deflection margin of the disc hook 15 can be secured on the shaft portion 14 side of the disc hook 15.

さらに、本実施形態によるヒンジロック機構によれば、ディスクフック１５が第２内径部２０a2，３０a2の内周に引っ掛かって第２内径部２０a2，３０a2の内周に固定されている状態においても、ディスクフック１５を支持する支持柱１６はディスクフック１５に対して回転可能な状態に保たれる。したがって、支持柱１６が先端に設けられたシャフト部１４は、ディスクフック１５が第２内径部２０a2，３０a2の内周に固定されている状態においても、ディスクフック１５とは独立に回転可能であり、ヒンジ装置１０，１０’が開閉自在に支持する一方の物体である便座および便蓋と共に回転する。   Furthermore, according to the hinge lock mechanism according to the present embodiment, the disc hook 15 is caught on the inner periphery of the second inner diameter portion 20a2, 30a2 and fixed to the inner periphery of the second inner diameter portion 20a2, 30a2. The support post 16 supporting the hook 15 is kept rotatable relative to the disc hook 15. Therefore, the shaft portion 14 provided with the support column 16 at its tip is rotatable independently of the disc hook 15 even in the state where the disc hook 15 is fixed to the inner periphery of the second inner diameter portion 20a2, 30a2. The hinges 10 and 10 'rotate together with the toilet seat and the toilet lid, which are one of the objects supported openably and closably.

便座および便器の物体間に取り付けられるヒンジ装置１０は、シャフト部１４が便蓋の不図示の取付穴を通され、便座に設けられた第１内径部２０a1に嵌合することで、シャフト部１４が便座の開閉に伴って回転し、ロータリーダンパ部１２によって便座の閉動作に抵抗が付与される。また、シャフト部１４が通される、便蓋に形成される不図示の取付穴は、中空円筒状をしており、シャフト部１４の平面部１４ｂに嵌合する壁部を備えていないため、シャフト部１４を空回りさせ、便蓋は便座の開閉動作に影響を受けない。   In the hinge device 10 attached between the toilet seat and the toilet bowl object, the shaft portion 14 is passed through a mounting hole (not shown) of the toilet lid and fitted to the first inner diameter portion 20a1 provided on the toilet seat, thereby the shaft portion 14 Is rotated with the opening and closing of the toilet seat, and the rotary damper unit 12 resists the closing operation of the toilet seat. Further, a mounting hole (not shown) formed in the toilet lid, through which the shaft portion 14 passes, has a hollow cylindrical shape and does not have a wall portion fitted to the flat portion 14 b of the shaft portion 14, The shaft portion 14 is idled, and the toilet lid is not affected by the opening and closing operation of the toilet seat.

一方、便蓋および便器の物体間に取り付けられるヒンジ装置１０’は、便蓋に第１内径部２０a1と同様な開口形状で形成された不図示の取付穴の第１内径部にシャフト部１４が嵌合することで、シャフト部１４が便蓋の開閉に伴って回転し、ロータリーダンパ部１２によって便蓋の閉動作に抵抗が付与される。また、シャフト部１４の先端に設けられたディスクフック１５は、不図示の取付穴の第１内径部を通された後、便座に設けられたホルダ部３０の取付穴３０ａにおける第２内径部３０a2に引っ掛けられる。ホルダ部３０の取付穴３０ａにおける第１内径部３０a1は前述したように中空円筒状をしているため、ヒンジ装置１０’のシャフト部１４は便座の開閉に伴って回転せず、空回りする。   On the other hand, in the hinge device 10 'attached between the toilet lid and the toilet bowl, the shaft portion 14 is formed in the first inner diameter portion of the attachment hole (not shown) formed in the toilet lid in the same opening shape as the first inner diameter portion 20a1. By fitting, the shaft portion 14 rotates with the opening and closing of the toilet lid, and the rotary damper portion 12 applies resistance to the closing operation of the toilet lid. Further, the disc hook 15 provided at the tip of the shaft portion 14 passes through the first inner diameter portion of the attachment hole (not shown), and then the second inner diameter portion 30a2 in the attachment hole 30a of the holder portion 30 provided in the toilet seat. It is hooked to Since the first inner diameter portion 30a1 in the mounting hole 30a of the holder portion 30 has a hollow cylindrical shape as described above, the shaft portion 14 of the hinge device 10 'does not rotate with the opening and closing of the toilet seat and rotates idle.

このため、ヒンジ装置１０’が開閉自在に支持する一方の物体である便蓋とは別の物体である便座に取付穴３０ａの第２内径部３０a2が形成され、その第２内径部３０a2にディスクフック１５が固定される場合、シャフト部１４が便蓋と共に回転しても、ディスクフック１５は、シャフト部１４の回転に伴って回転しない。よって、ディスクフック１５がシャフト部１４の回転に伴って回転することで、ディスクフック１５が固定されている便座の取付穴３０ａとの間に摩擦を生じて、便座の取付穴３０ａを傷付けることはない。また、便座が回転して便座と共にディスクフック１５が回転しても、その回転に伴ってヒンジ装置１０’のシャフト部１４が回転することはないため、ヒンジ装置１０’が便座の回転に影響されることはない。   Therefore, the second inner diameter portion 30a2 of the mounting hole 30a is formed in the toilet seat which is an object different from the toilet lid which is one of the objects supported by the hinge device 10 'in an openable / closable manner. When the hook 15 is fixed, the disc hook 15 does not rotate with the rotation of the shaft portion 14 even when the shaft portion 14 rotates with the toilet lid. Therefore, the disc hook 15 rotates with the rotation of the shaft portion 14 to generate friction between the disc hook 15 and the mounting hole 30a of the toilet seat to which the disc hook 15 is fixed, thereby damaging the toilet seat mounting hole 30a. Absent. Also, even if the toilet seat rotates and the disc hook 15 rotates with the toilet seat, the shaft portion 14 of the hinge device 10 'does not rotate with the rotation, so the hinge device 10' is affected by the rotation of the toilet seat. There is nothing to do.

図６（ａ）は、一実施形態の第１変形例によるヒンジロック機構が適用されたヒンジ装置１０Ａの一部破断側面図である。なお、図６において図５と同一または相当する部分には同一符号を付してその説明は省略する。   FIG. 6 (a) is a partially broken side view of a hinge device 10A to which a hinge lock mechanism according to a first modification of one embodiment is applied. 6 that are the same as or correspond to those in FIG. 5 are assigned the same reference numerals and descriptions thereof will be omitted.

このヒンジ装置１０Ａでは、支持柱１６Ａがシャフト部１４と別体にアダプタとして形成される。支持柱１６Ａは、先端側に大径部１６A1が短く、根元側に小径部１６A2が長く形成され、小径部１６A2の外周に雄ネジが形成されている。また、シャフト部１４の先端には、シャフト部１４の軸方向に開口したネジ穴１４ｃの内周に雌ネジが形成されている。支持柱１６Ａは、小径部１６A2の雄ネジがネジ穴１４ｃの雌ネジと螺合して、シャフト部１４の先端に取り付けられる。なお、大径部１６A1の先端には上述のカシメ代１６ａが形成されており、ディスクフック１５が上記の実施形態と同様にカシメによって取り付けられている。   In the hinge device 10A, the support post 16A is formed as an adapter separately from the shaft portion 14. In the support column 16A, the large diameter portion 16A1 is short on the tip end side, the small diameter portion 16A2 is formed long on the root side, and a male screw is formed on the outer periphery of the small diameter portion 16A2. Further, at the tip of the shaft portion 14, a female screw is formed on the inner periphery of a screw hole 14c opened in the axial direction of the shaft portion 14. The support pillar 16A is attached to the tip of the shaft portion 14 by screwing the male screw of the small diameter portion 16A2 with the female screw of the screw hole 14c. The above-mentioned caulking margin 16a is formed at the end of the large diameter portion 16A1, and the disc hook 15 is attached by caulking as in the above embodiment.

この第１変形例によるヒンジロック機構によれば、シャフト部１４と別体に形成された支持柱１６Ａがシャフト部１４の先端に螺合して取り付けられるため、支持柱１６Ａをシャフト部１４に対して相対的に回すことで、支持柱１６Ａがシャフト部１４の先端から突出する長さを調整することができる。このため、ディスクフック１５が第２内径部２０a2，３０a2の内周に引っ掛かって固定される位置を、第２内径部２０a2，３０a2の深さに応じて所望の位置に設定することができる。また、実機の便座における第２内径部２０a2，３０a2の実際の形状に応じて、ディスクフック１５の第２内径部２０a2，３０a2内周への引っ掛かり具合が丁度よい深さに、ディスクフック１５の固定位置を設定することができる。   According to the hinge lock mechanism according to the first modification, the support post 16A formed separately from the shaft portion 14 is screwed to the tip end of the shaft portion 14 and thus the support post 16A is attached to the shaft portion 14 The relative length by which the support post 16A protrudes from the tip of the shaft portion 14 can be adjusted by rotating the shaft relatively. Therefore, the position at which the disc hook 15 is fixed by being caught on the inner circumference of the second inner diameter portion 20a2, 30a2 can be set to a desired position according to the depth of the second inner diameter portion 20a2, 30a2. In addition, depending on the actual shape of the second inner diameter portion 20a2, 30a2 in the toilet seat of the actual machine, the disk hook 15 is fixed to a depth that the hooking condition of the disk hook 15 on the inner periphery of the second inner diameter portion 20a2, 30a2 is just good. You can set the position.

図６（ｂ）は、一実施形態の第２変形例によるヒンジロック機構が適用されたヒンジ装置１０Ｂの一部破断側面図である。   FIG. 6 (b) is a partially broken side view of a hinge device 10B to which a hinge lock mechanism according to a second modification of one embodiment is applied.

このヒンジ装置１０Ｂでも、支持柱１６Ｂがシャフト部１４と別体にアダプタとして形成される。支持柱１６Ｂは、長い大径部１６B1の端部に小径部１６B2が短く形成され、シャフト部１４の先端にシャフト部１４の軸方向に開口した開口部１４ｄに出し入れ自在に収納される。ヒンジ装置１０Ｂが取付穴２０ａ，３０ａに挿入されると、支持柱１６Ｂは、開口部１４ｄに内蔵された弾性部材である圧縮コイルスプリング１７によって、第２内径部２０a2，３０a2の深部側に付勢される。圧縮コイルスプリング１７は、一端部が開口部１４ｄの底部に形成されたボス１４ｅに、他端部が支持柱１６Ｂの小径部１６B2に圧入され、開口部１４ｄから抜け出るのが防がれている。なお、大径部１６B1の先端には上述のカシメ代１６ａが形成されており、ディスクフック１５が上記の実施形態と同様にカシメによって取り付けられている。   Also in the hinge device 10B, the support post 16B is formed as an adapter separately from the shaft portion 14. The small diameter portion 16B2 is formed short at the end of the long large diameter portion 16B1 of the support column 16B, and is inserted in and removed from the opening 14d opened in the axial direction of the shaft portion 14 at the tip of the shaft portion 14. When the hinge device 10B is inserted into the mounting holes 20a and 30a, the support post 16B is urged toward the deep side of the second inner diameter portion 20a2 and 30a2 by the compression coil spring 17 which is an elastic member contained in the opening 14d. Be done. One end of the compression coil spring 17 is press-fit into a boss 14e formed at the bottom of the opening 14d, and the other end is press-fit into the small diameter portion 16B2 of the support column 16B to prevent the compression coil spring 17 from coming out of the opening 14d. The above-mentioned caulking margin 16a is formed at the end of the large diameter portion 16B1, and the disc hook 15 is attached by caulking as in the above embodiment.

この第２変形例によるヒンジロック機構によれば、シャフト部１４が取付穴２０ａ，３０ａに挿入されてディスクフック１５が第２内径部２０a2，３０a2に差し込まれた状態において、開口部１４ｄに内蔵された圧縮コイルスプリング１７によって第２内径部２０a2，３０a2の深部側に支持柱１６Ｂが付勢されることで、ディスクフック１５も第２内径部２０a2，３０a2の深部側に付勢される。このため、ヒンジ装置１０Ｂの取付穴２０ａ，３０ａへの組み込み後において、ディスクフック１５が第２内径部２０a2，３０a2の深部側に常に付勢されることで、ディスクフック１５は第２内径部２０a2，３０a2から抜けないその深部側の方向へ常に押されるので、ディスクフック１５の第２内径部２０a2，３０a2内周への保持安定性が高められる。また、ヒンジ装置１０Ｂの取付穴２０ａ，３０ａへの組み込み時において、シャフト部１４先端のディスクフック１５が取付穴２０ａ，３０ａの周囲に当たると、ディスクフック１５が一旦引っ込むので、この引っ込みがシャフト部１４の先端を取付穴２０ａ，３０ａに挿入する案内になって、シャフト部１４の先端を取付穴２０ａ，３０ａに挿入し易くなり、ヒンジ装置１０Ｂの取付穴２０ａ，３０ａへの組み込み性が向上する。   According to the hinge lock mechanism according to the second modification, the shaft portion 14 is inserted into the mounting holes 20a, 30a, and the disc hook 15 is inserted into the second inner diameter portion 20a2, 30a2. The support hook 16B is biased to the deep side of the second inner diameter portion 20a2, 30a2 by the compression coil spring 17, and the disc hook 15 is also biased to the deep side of the second inner diameter portion 20a2, 30a2. Therefore, the disc hook 15 is always urged to the deep side of the second inner diameter portion 20a2, 30a2 after the hinge device 10B is assembled in the mounting holes 20a, 30a, whereby the disc hook 15 is moved to the second inner diameter portion 20a2. Since the disc hook 15 is always pushed in the direction of the deep side which does not come off, the holding stability of the disc hook 15 to the inner periphery of the second inner diameter portion 20a2, 30a2 is enhanced. In addition, when the disc hook 15 at the tip of the shaft portion 14 hits the periphery of the mounting holes 20a and 30a when the hinge device 10B is installed in the mounting holes 20a and 30a, the disc hook 15 is temporarily retracted. The tip of the shaft portion 14 is guided into the mounting holes 20a and 30a, so that the tip of the shaft portion 14 can be easily inserted into the mounting holes 20a and 30a, and the incorporation of the hinge device 10B into the mounting holes 20a and 30a is improved.

なお、上述した実施形態および各変形例では、係止部材を構成するディスクフック１５が、図４に示す、外周に凸部１５ｂが形成された円盤状部材から形成される場合について説明した。しかし、係止部材の形状はこれに限定されることはない。例えば、図７（ａ）および（ｂ）の正面図および側面図に示すディスクフック１８のように、外周に複数の切り欠き部１８ａ、中央部に穴１８ｂが形成された円盤状部材で、外周がシャフト部１４の側に傾斜するように、係止部材を構成してもよい。また、図７（ｃ）および（ｄ）の正面図および側面図に示すディスクフック１９のように、外周が円形をし、中央部に穴１９ａが形成された円盤状部材で、外周がシャフト部１４の側にすり鉢状に傾斜するように、係止部材を構成してもよい。   In the embodiment and the modifications described above, the case where the disc hook 15 constituting the locking member is formed of a disk-like member having the convex portion 15 b formed on the outer periphery shown in FIG. 4 has been described. However, the shape of the locking member is not limited to this. For example, a disk-like member having a plurality of notches 18a in the outer periphery and a hole 18b in the center like the disk hook 18 shown in the front view and the side view of FIGS. 7 (a) and 7 (b) The locking member may be configured to be inclined toward the shaft portion 14 side. 7 (c) and (d) is a disk-like member having a circular outer periphery and a hole 19a formed at its central portion like the disk hook 19 shown in the front view and the side view of FIG. The locking member may be configured to be bevelled towards the 14 side.

また、上述した実施形態および各変形例では、カシメ代１６ａにディスクフック１５がカシメによって取り付けられる場合について、説明した。しかし、図７（ｅ）に示すように、支持柱１６，１６Ａ，１６Ｂの先端に、溝１６ｃが形成された取付代１６ｂを設け、この溝１６ｃにディスクフック１５，１８，１９の穴１５ｂ，１８ｂ，１９ａを嵌めて、ディスクフック１５，１８，１９をシャフト部１４の先端に取り付けるようにしてもよい。この場合にも、ディスクフック１５，１８，１９は、支持柱１６，１６Ａ，１６Ｂからシャフト部１４の軸方向に抜けず、かつ、支持柱１６，１６Ａ，１６Ｂに回転自在に、支持柱１６，１６Ａ，１６Ｂに取り付けられる。   Moreover, in the embodiment and each modification described above, the case where the disc hook 15 is attached to the caulking margin 16 a by caulking has been described. However, as shown in FIG. 7 (e), a mounting margin 16b having a groove 16c is provided at the tip of the support posts 16, 16A, 16B, and the holes 15b of the disc hooks 15, 18, 19 are formed in the groove 16c. The disc hooks 15, 18, 19 may be attached to the tip of the shaft portion 14 by fitting the 18b, 19a. Also in this case, the disc hooks 15, 18, 19 do not come off from the support posts 16, 16A, 16B in the axial direction of the shaft portion 14, and can freely rotate to the support posts 16, 16A, 16B. It is attached to 16A and 16B.

このような各構成によっても上述した実施形態および各変形例と同様な作用効果が奏される。   The same operation and effect as those of the above-described embodiment and each modification can be obtained by such configurations.

上記実施形態では、本発明によるヒンジロック機構を洋式トイレのヒンジ装置に適用した場合について、説明した。しかし、本発明によるヒンジロック機構は、洋式トイレのヒンジ装置に限ることなく、物体間を開閉自在に支持する他のヒンジ装置にも同様に適用することが出来、上記の実施形態および各変形例と同様な作用効果が奏される。   In the above embodiment, the case where the hinge lock mechanism according to the present invention is applied to the hinge device of the Western-style toilet has been described. However, the hinge lock mechanism according to the present invention is not limited to the hinge device of the Western-style toilet, but can be similarly applied to other hinge devices which open and close support between objects, and the above embodiment and each modification The same function and effect as the above are exhibited.

課題を解決するための手段
［０００６］
本発明はこのような課題を解決するためになされたもので、
物体間を開閉自在に支持するヒンジ装置がそのシャフト部が挿入される取付穴から抜けるのを防ぐヒンジロック機構において、
シャフト部に嵌合する内径形状を有する第１内径部と、シャフト部の外径より小さな内径をして第１内径部の最深部に第１内径部に連なって開口する第２内径部とが取付穴に形成され、
シャフト部と別体に形成されて外周に雄ネジが形成され、シャフト部の先端にシャフト部の軸方向に開口したネジ穴の内周に形成された雌ネジと螺合して、シャフト部の先端に取り付けられ、第２内径部の内径より小さな外径をしてシャフト部の先端に突出し、第２内径部に差し込まれる支持柱と、
第２内径部の内径と同等以上の外径をして弾性を有し、第２内径部に差し込まれて外周が第２内径部の内周に引っ掛かる、支持柱に支えられてシャフト部の先端に取り付けられる係止部材とを備える
ことを特徴とする。
また、本発明は、
物体間を開閉自在に支持するヒンジ装置がそのシャフト部が挿入される取付穴から抜けるのを防ぐヒンジロック機構において、
シャフト部に嵌合する内径形状を有する第１内径部と、シャフト部の外径より小さな内径をして第１内径部の最深部に第１内径部に連なって開口する第２内径部とが取付穴に形成され、

ことを特徴とする。
［０００７］
本構成によれば、ヒンジ装置のシャフト部が取付穴に挿入されると、シャフト部が第１内径部に嵌合すると共に、シャフト部の先端に備えられる係止部材が第２内径部に差し込まれる。この際、係止部材はその弾性によって撓んで弾性変形して第２内径部に入り込み、その外周が第２内径部の内周に引っ掛かる。先端にこの係止部材を備えるシャフト部は、取付穴から抜き取る力がかかっても、係止部材が第２内径部の内周に引っ掛かってこの抜き取る力に対抗するので、取付穴から抜けなくなり、ヒンジ装置は取付穴から抜けなくなる。したがって、従来のスプリングクリップ等の固定具を使用することなく、ヒンジ装置を取付穴から抜けなくすることが出来る。このため、スプリングクリップ等の固定具をヒンジ装置と別に用意する必要がなくなり、スプリングクリップ等の固定具をヒンジ装置とは別個に管理する管理工程を削減することが出来る。また、スプリングクリップ等の固定具をホルダ部に通すための挿入孔が不要になり、ホルダ部に挿入孔を設ける加工工程を削減することが出来る。この結果、ヒンジ装置を使ったトイレの製造時や、便座[0002]
At the time of manufacturing the toilet seat and the toilet lid, a processing step of providing an insertion hole in the holder portion is also required. For this reason, conventionally, these management steps and processing steps have been the burden of cost and work in manufacturing the toilet, toilet seat and lid.
Means for Solving the Problem [0006]
The present invention has been made to solve such problems.
In a hinge lock mechanism which prevents a hinge device for openably and closably supporting objects from coming out of a mounting hole into which the shaft portion is inserted,
A first inner diameter portion having an inner diameter shape fitted to the shaft portion, and a second inner diameter portion having an inner diameter smaller than the outer diameter of the shaft portion and being continuous with the first inner diameter portion at the deepest portion of the first inner diameter portion Formed in the mounting hole,
An external thread is formed on the outer periphery separately from the shaft portion, and is screwed with an internal thread formed on the inner periphery of a screw hole opened in the axial direction of the shaft portion at the tip of the shaft portion. A support column attached to the tip, having an outer diameter smaller than the inner diameter of the second inner diameter portion and projecting to the tip of the shaft portion and inserted into the second inner diameter portion;
The outer diameter is equal to or larger than the inner diameter of the second inner diameter portion to have elasticity, and inserted into the second inner diameter portion, the outer periphery is caught on the inner periphery of the second inner diameter portion, supported by the support column, and the tip of the shaft portion And a locking member attached to the housing.
Also, the present invention is
In a hinge lock mechanism which prevents a hinge device for openably and closably supporting objects from coming out of a mounting hole into which the shaft portion is inserted,
A first inner diameter portion having an inner diameter shape fitted to the shaft portion, and a second inner diameter portion having an inner diameter smaller than the outer diameter of the shaft portion and being continuous with the first inner diameter portion at the deepest portion of the first inner diameter portion Formed in the mounting hole,
It is formed separately from the shaft portion and is accommodated at an end of the shaft portion so as to be freely inserted in and removed from the opening portion opened in the axial direction of the shaft portion, and attached to the deep portion side of the second inner diameter portion by an elastic member incorporated in the opening portion A supporting column which is biased and which has an outer diameter smaller than the inner diameter of the second inner diameter portion and which protrudes to the tip of the shaft portion and which is inserted into the second inner diameter portion;
The outer diameter is equal to or larger than the inner diameter of the second inner diameter portion to have elasticity, and inserted into the second inner diameter portion, the outer periphery is caught on the inner periphery of the second inner diameter portion, supported by the support column, and the tip of the shaft portion And a locking member attached to the housing.
[0007]
According to this configuration, when the shaft portion of the hinge device is inserted into the mounting hole, the shaft portion is fitted into the first inner diameter portion, and the locking member provided at the tip of the shaft portion is inserted into the second inner diameter portion. Be At this time, the locking member is bent and elastically deformed by its elasticity and enters the second inner diameter portion, and the outer periphery thereof is caught on the inner periphery of the second inner diameter portion. The shaft portion provided with the locking member at the tip does not come out of the mounting hole because the locking member is caught on the inner periphery of the second inner diameter portion and resists the pulling out force even if a force to pull out from the mounting hole is applied. The hinge device does not come out of the mounting hole. Therefore, the hinge device can be prevented from coming out of the mounting hole without using a fixing device such as a conventional spring clip. For this reason, it is not necessary to prepare fixtures, such as a spring clip, separately from a hinge apparatus, and the management process which manages fixtures, such as a spring clip, separately from a hinge apparatus can be reduced. Moreover, the insertion hole for passing fixing tools, such as a spring clip, through a holder part becomes unnecessary, and the processing process which provides an insertion hole in a holder part can be reduced. As a result, when the toilet is manufactured using the hinge device,

・便蓋の製造時におけるコスト面および作業面の負担を軽減することが出来る。
また、支持柱を介してシャフト部の先端に係止部材が取り付けられる本構成によれば、係止部材のシャフト部先端への取り付けが容易になると共に、係止部材の撓み代を係止部材のシャフト部側に確保することが出来る。
また、本構成によれば、シャフト部と別体に形成された支持柱がシャフト部の先端に螺合して取り付けられるため、支持柱をシャフト部に対して相対的に回すことで、支持柱がシャフト部の先端から突出する長さを調整することができる。このため、係止部材が第２内径部の内周に引っ掛かって固定される位置を、第２内径部の深さに応じて所望の位置に設定することができる。また、第２内径部の実際の形状に応じて、係止部材の第２内径部内周への引っ掛かり具合が丁度よい深さに、係止部材の固定位置を設定することができる。
また、本構成によれば、シャフト部が取付穴に挿入されて係止部材が第２内径部に差し込まれた状態において、開口部に内蔵された弾性部材によって第２内径部の深部側に支持柱が付勢されることで、係止部材も第２内径部の深部側に付勢される。このため、ヒンジ装置の取付穴への組み込み後において、係止部材が第２内径部の深部側に常に付勢されることで、係止部材は第２内径部から抜けないその深部側の方向へ常に押されるので、係止部材の第２内径部内周への保持安定性が高められる。また、ヒンジ装置の取付穴への組み込み時において、シャフト部先端の係止部材が取付穴の周囲に当たると、係止部材が一旦引っ込むので、この引っ込みがシャフト部先端を取付穴に挿入する案内になって、シャフト部先端を取付穴に挿入し易くなり、ヒンジ装置の取付穴への組み込み性が向上する。
［０００８］
また、本発明は、係止部材が、外周に複数の凸部が形成された円盤状部材、または、外周に複数の切り欠き部が形成された円盤状部材、または、外周が円形をした円盤状部材であって、外周がシャフト部側に傾斜していることを特徴とする。
［０００９］
本構成によれば、シャフト部に取付穴から抜き取る力がかかると、係止部材の外周が第２内径部の内周に噛み込む。このため、係止部材がシャフト部を抜き取る力に対抗する力は大きくなり、ヒンジ装置は堅固に取付穴から抜けなくなる。また、係止部材の外周がシャフト部側に傾斜しているので、シャフト部に取付穴から抜き取る力がかかると、係止部材の外周は第２内径部の内周により鋭く噛み込む。このため、ヒンジ装置はより堅固に取付穴から抜けなくなる。また、係止部材の外周がシャフト部側に傾斜していると、シャフト部を取付穴に挿入する際、係止部材はスムーズに第２内径部に入り込み、ヒンジ装置の取付穴への組み込み性が向上する。
［００１０］
［００１１］
［００１２］
また、本発明は、係止部材が、支持柱からシャフト部の軸方向に抜けず、かつ、支持柱に回転自在に、支持柱に取り付けられることを特徴とする。
［００１３］
本構成によれば、係止部材が第２内径部の内周に引っ掛かって第２内径部の内周に固定されている状態においても、係止部材を支持する支持柱は係止部材に対して回転可能な状態に保たれる。したがって、支持柱が先端に設けられたシャフト部は、係止部材が第２内径部の内周に固定されている状態に[0003]
-It is possible to reduce the burden of cost and work at the time of manufacturing the toilet lid.
Further, according to the present configuration in which the locking member is attached to the tip of the shaft portion via the support column, attachment of the locking member to the tip of the shaft portion is facilitated, and the bending margin of the locking member is used as the locking member. Can be secured on the shaft side of the
Further, according to the present configuration, since the support column separately formed from the shaft portion is screwed to the tip end of the shaft portion, the support column can be rotated relative to the shaft portion. Can adjust the length which protrudes from the front-end | tip of a shaft part. For this reason, the position where the locking member is caught and fixed on the inner periphery of the second inner diameter portion can be set to a desired position according to the depth of the second inner diameter portion. Further, according to the actual shape of the second inner diameter portion, the fixing position of the locking member can be set to such a depth that the degree of engagement of the locking member to the inner periphery of the second inner diameter portion is just right.
Further, according to the present configuration, in a state in which the shaft portion is inserted into the mounting hole and the locking member is inserted into the second inner diameter portion, the support is supported on the deep portion side of the second inner diameter portion By biasing the post, the locking member is also biased to the deep side of the second inner diameter portion. Therefore, the locking member is always urged to the deep side of the second inner diameter portion after the hinge device is installed in the mounting hole, and the direction of the deep side where the locking member does not come off the second inner diameter portion The holding stability of the locking member to the inner circumference of the second inner diameter portion is enhanced. In addition, when the locking member at the tip of the shaft portion hits the periphery of the mounting hole at the time of installation in the mounting hole of the hinge device, the locking member once retracts, and this retraction leads to a guide for inserting the shaft tip into the mounting hole. Thus, the tip of the shaft portion can be easily inserted into the mounting hole, and the incorporation of the hinge device into the mounting hole is improved.
[0008]
Further, according to the present invention, the locking member is a disk-like member having a plurality of projections formed on the outer periphery, or a disk-like member having a plurality of cutouts formed on the outer periphery, or a disk having a circular outer periphery. And the outer periphery is inclined toward the shaft portion.
[0009]
According to this configuration, when the shaft portion is pulled out from the mounting hole, the outer periphery of the locking member is engaged with the inner periphery of the second inner diameter portion. For this reason, the force against the force with which the locking member pulls out the shaft portion increases, and the hinge device does not firmly come out of the mounting hole. Further, since the outer periphery of the locking member is inclined toward the shaft portion side, when the shaft portion is pulled out from the mounting hole, the outer periphery of the locking member is sharply bitten by the inner periphery of the second inner diameter portion. Because of this, the hinge device does not come out of the mounting hole more firmly. Further, when the outer periphery of the locking member is inclined toward the shaft portion side, when inserting the shaft portion into the mounting hole, the locking member smoothly enters the second inner diameter portion, and the incorporation of the hinge device into the mounting hole Improve.
[0010]
[0011]
[0012]
Further, the present invention is characterized in that the locking member is attached to the support column so as not to slip out of the support column in the axial direction of the shaft portion and to be rotatable on the support column.
[0013]
According to this configuration, even in the state where the locking member is caught on the inner periphery of the second inner diameter portion and fixed to the inner periphery of the second inner diameter portion, the support column supporting the locking member is against the locking member Can be kept rotatable. Therefore, in the shaft portion provided with the support column at the tip, the locking member is fixed to the inner periphery of the second inner diameter portion.

【０００４】
おいても、係止部材とは独立に回転可能であり、ヒンジ装置が開閉自在に支持する一方の物体と共に回転する。このため、ヒンジ装置が開閉自在に支持する一方の物体（例えば便蓋）とは別の物体（例えば便座）に取付穴の第２内径部が形成され、その第２内径部に係止部材が固定される場合、一方の物体に形成された取付穴の第１内径部に嵌合するシャフト部が一方の物体と共に回転しても、係止部材は、シャフト部の回転に伴って回転しない。よって、係止部材がシャフト部の回転に伴って回転することで、係止部材が固定されている別の物体との間に摩擦を生じて、別の物体を傷付けることはない。また、別の物体が回転して別の物体と共に係止部材が回転しても、その回転に伴ってシャフト部が回転することはないため、ヒンジ装置が別の物体の回転に影響されることはない。
［００１４］
［００１５］
［００１６］
［００１７］[0004]
Also, it is rotatable independently of the locking member, and the hinge device rotates with one of the objects supported openably and closably. For this reason, the second inner diameter portion of the mounting hole is formed in an object (for example, a toilet seat) different from one of the objects (for example, the toilet lid) that the hinge device supports openably and closably. When fixed, even if the shaft portion fitted in the first inner diameter portion of the mounting hole formed in one object rotates with one object, the locking member does not rotate with the rotation of the shaft portion. Thus, the rotation of the locking member with the rotation of the shaft does not cause friction with another object to which the locking member is fixed, and does not damage another object. In addition, even if another object rotates and the locking member rotates with another object, the hinge does not rotate with the rotation, so that the hinge device is affected by the rotation of the other object. There is no.
